This example demonstrates how to generate a checkerboard dataset and bicluster it using the Spectral Biclustering algorithm. The data is

This shows an example of a neighbors-based query (in particular a kernel density estimate) on geospatial data, using a Ball Tree built upon

Plot the confidence ellipsoids of each class and decision boundary print(__doc__)

An example using IsolationForest for anomaly detection. The IsolationForest ?isolates? observations by randomly selecting a feature and then randomly selecting

These figures aid in illustrating how a point cloud can be very flat in one direction?which is where PCA comes in to choose a direction that is not flat.

Fit regression model with Bayesian Ridge Regression. See

This example illustrates the need for robust covariance estimation on a real data set. It is useful both for outlier detection and for a better understanding
